UNITED/STATES PATENT OFFICE. 1

FRANKLIN G. HOBART, or BnLorr, WISCONSIN, ASSIGNOR 'ro FAIRBANKS, monsis AND COMPANY, OF CHICAGO, ILLINOIS, A CQRPQR-ATION ILLINOIS WATER-SEALED" PRODUCER VALVE To all whom it may concern: Be it known that I, FRANKLIN Gr. Homer,

a citizen of the United States, residing at Beloit, in the county of Rock-and State of -Wisconsin; have invented a certain new and his invention relates to liquid sealedvalves for use in the pipe connecting the producer and scrubber of an ordlnar gas plant, particularly where such valve 1s de-' signed, to operate at the will ofthe operator, to permit the gas to passfrom the producer into the scrubber or into the open air, as desired. Valves various kinds including complish this purpose.

The object of this invention is to rovrde valve indicated. v

The invention consists; in :1 wire for the purpose named so constructed and located with reference to the otl er'parts of the device between which it is connected that the valve itself is continually su plied with the waste aterfrom one of the evioes to-which it is connected thereby doing away with the necessity of an Independent water supply therefor and alwu vs insuringthe proper operation of the valve;' in novel-means for op-' crating the val ve from outside the device and in the peculiar location of. theoperating lneuns; infithe use of the form and arrangement of valve shown to act as a trap for the discharge of water from; the scrubber to a sewer orthe like so as to prevent retu r11 of either water or gas.

The invention'also' consists in particular details of construction adapted to bring about the general results desired and in other features which will be more fully, pointed out as the specification proceeds.

Referring to the drawings, Figure 1 is a vertical sectional cent-er view through a gas plantof the type described to which the device of this invention is applied. Fig. 2 is 9. Ian view of the valve and portions of the a j-ucent walls of the producer and scrubber Fig. 3 is asectional vertical detail view on the line 33, Fig. 2 showing the valve of this invention in one extreme position and Fig. 4. shows the same parts-of the valve moved to the oppo- Specification of Lettersfatcnt.

plan view onthe. line 5- 5, of Fig. 4.

The parts at the left hand half of F 1 designated by the numeral 8 represent a similarly the parts occupying most of the right hand'ha-lf of this figure and carrying the numeral 10 represent a scrubber'of the type well known in the art for use in con-. nection with the producer 8, the producer some sort of a pipe such as 12 through which the gas made by the )roducer 8 passes to of this invention is located, the preferred inthis pipe 12 said pipe is provlded with a flange 14 connected by any suitable means to .the flan e 16 on upper portion of the opposite end of this upper casin 20 is a to the flange on the scrubber. This-up per casing 20 is provi ed wi ran internal pipe -26 having the dew nward turned orifice or end 28' around which is an annular space 30, usually, but not necessarily of circular cross section, as shown. The orifice 3.1 openin 'into pipe 12 is considerably above the l orifice 33 leading from pi )e 26 to the waste water compartment 35 0 is also above the lower end of pipe 28. result of this latter construction is that water from compartment 35 flows continuously turned end. This up or section 20 of the valve casing is provi ed with a horizontal flange 32 to which the 'lower valve casin 34 is attached by means of the flange 361m any suitable connectors. On the inside; of this lower casing member 34 is a vertical tubular member '38 of approximately the same diameter as the member 28 and around this tubular member 38 and between it and 40. The interior of this pipe 38 is connected by means of the flanges 42 to a pipe 44 open at its upper end 46 to the open air water sealed check valve 48 of ordinary construction leading to the pipe 50 through which any surplus water in the water space 52 may escape. The valve 48 and the pipe gas producer of the'ordinary type while.

and scrubber being connected together by wall 18 of t 1e upper casing 20, while at theflange 22 connected by any suita le means the scrubber 10'- The.

into pipe 28 and out of its downward.

the exterior casing 34 is an annular space site extreme position. Fig. is a sectional the scrubber 1.0 for t e purpose of being cleaned. .In this pipe 12 the :valve device form being shown. In mo ntingthe valve as ower end of the pipe 28. The

This pipe 44 also has at its lower end a 50 are accessible by means of a removable hand plate 54. Similarly the interioi" of the upper portion of the casing and the. pipe 28 may be ins ected b removing the cover plate 56 detac ably he d in place, as shown in Figs. 2 and 4 by means of the sealing bar 58 andset screw 60. y

Interposed between the members 28 and 88 and within the casing, as shown, is the valve member proper 62 preferably of cylin; drical form having its lower end 64 adapted to incloser the cylindrical pipe member 38 when the valve is in-the position of Fig. 3

and its upper end 66 adapted to inclose the downwardly turned pipe member 28 when the valve is moved'to the position of Fig. 4.

Across the interior of this valve member 62 at approximately its middle is an imperiorate bottom 68 with the result that a. receptacle 70 for wateror other-liquid is formed within the valve member 62. Attentiou is 1 here particularly. called to the fact that this water receptacle 70 being below the downwardly turned .orifice of pipe 28,'t'hrough which waste water coming from the. scrubber waste 'chamber35 passes, and water always being present in said chamber and in pipe 26, this receptacle 70 is always kept full of water with the re sult that when the valveis moved to the position of Fig. 4 it absolutely seals the lower end of the pipe 28 and prevents the discharge of gas from the producer to the scrubber and this is done without the aid of an external water supply and pipetherefor as has been the practice heretofore. While in this position the water coming from the pipe 28 passes down through the'annular space 72 between the cylindrical member 62 and its guidin ply to insure t e proper vertical movement "of the valve) and thus fills upthe annular space. 40 from which the overflow always passes into the. pipe 38, and thence through the valve 48 to the pipe 50. When the parts.

.. are in the position of Fig. 4 the gas passes throu h pipes 12, 72 38 and 44 and thence out 0 its end '46 to the open air. The valve member 62 may be lifted and owered by any suitable means; one Iform consisting in a lever 7 8 pivoted at 80, having oneend connected to a rod 82 attached to the bottom 68 of water receptacle 70, and the other end of said lever being-connected by the-rod 84 and crank pin 86, to a crank arm 88-pivoted at 90 land operated by a lever handle 92. Rotatin this handle 92 (which'is located outside 0% the pipe 44, the

remaining connections being within the pipe flanges 74, (provided simre shown- 44 and passageway 38) from the position of Fig. 3 to that of Fi 4 and back again moves the parts as. an for the pur osesfset forth. When the'parts are moved rom the position of Fig. 4 to that of Fig. 3 the gas entering from pipe 12 through orifice 31 passes into pi e 28 and out of opening 33 into the scrubber but during this 0 eration water is still flowing from the scrub er first into receptacle 70, then into annular space 40 from which it passes between parts 64 and 38 into p'pe 38 and thence out through pipe 50 as before.

Having thus described my in ention what i I claim as new and desire to secure by Letters Patent is 1. Ina device of the classdescribed the "combination of a gas producer, a scrubber.

a pipe connecting them, a valve casing mounted in said pipe, a valve in the casing constructed to move from a position in which it passes gas from the producer to the scrubber, to a position in which it. excludes the gas from the scrubber and passes it' out of another opening in the casing, said valve being also constructed to receive and pass waste water from the scrubber through't-he valve in all of its positions, the water in so doing serving as a seal for the valve for the purposes set forth.

2. In a device of the class described the combination of a gas producerand scrubber therefor, a pipe connecting them, a valvecasing mounted in said pipe, a valve within said"casi'ng movable {to two different positions, in 'one. posit1on adm tting gas from the producer to the scrubber and in the other position shutting off the gas from the scrub er andadmitting it to a discharge opening within the casing, a source of Waste water within the scrubber so located that it passes continuously through the valve casing and through parts of the valve so constructed as to seal the valve and then passescon- 'tinuously outjfrom the last mentioned discharge opening and a supplemental trap adjacent to said last mentioned discharge openlng'and connected to a waste pipe or sewer adapted to pass said water therethrough without permitting the return of gas for the purposes set forth.

In witness whereof, I havc'hereunto subscribed my name in the presence of two witnesses. 4 FRANKLIN G. HOBAR Witnesses:
